Abstract: ABSTRACT OF THE DISCLOSURE    A thermochemical cyclic process for producing hydrogen from water comprises reacting ceric oxide with monobasic or dibasic alkali metal phosphate to yield a solid reaction product, oxygen and water.  The solid reaction product, alkali metal carbonate or bicarbonate, and water, are reacted to yield hydrogen, ceric oxide, carbon dioxide and trialkali metal phosphate.  Ceric oxide is recycled.  Trialkali metal phosphate, carbon dioxide and water are reacted to yield monobasic or dibasic alkali metal phosphate and alkali metal bicarbonate, which are recycled.  The cyclic process can be modified for producing carbon monoxide from carbon dioxide by reacting the alkali metal cerous phosphate and alkali metal carbonate or bicarbonate in the absence of water to produce carbon monoxide, ceric oxide, carbon dioxide and trialkali metal phosphate.  Carbon monoxide can be converted to hydro-gen by the water gas shift reaction.

Abstract: APPARATUS AND METHOD FOR DETECTION OF OVERLAPPING OBJECTS            Abstract of the Disclosure Method and means are disclosed for detection of overlapped sheets transported along a path.  A plurality of detection means are aligned substantially perpendicular to the direction of movement of said sheets, each detection means including one or more radiation sources and one or more radiation detectors. The overlapping of one sheet by another produces a shadow on the surface of the overlapped sheet along the edge of the overlapping sheet when radiation is directed obliquely on to the sheets from one of said radiation sources, the direction of such radiation necessary to produce a shadow being dependent on the direction of the overlap of one sheet by another. Reflected radiation from the sheets is received by one or more of the radiation detectors, and shadows or marks on the sheets are detected by reason of their lower reflectivity.  Shadows indicating overlapped edges are distinguished from marks on the sheets by logic circuitry which signifies the presence of an overlap when one but not both of two samplings of the radiation detectors of all the radiation means shows a decrease in reflectivity.

Abstract: ABSTRACT OF THE DISCLOSURE           Dry and liquid feed supplements are recovered from treating animal wastes collected from a confinement feeding area for livestock and the like by a closed loop type of collection system including a primary liquid storage tank.  Solids and liquids are separated from the collected wastes by dynamic liquid filtering apparatus including a unique compression filter.  Liquid is withdrawn near the surface of the primary tank, passed through a second solid/liquid separating filter and transferred to a secondary tank.  Preferably rarified oxygen is forced into both tanks so as to aerate the liquids.  After appropriate aerobic digestion or oxidation, the secondary tank liquids are used to supplement feed water and the solids are used to supplement dry feed ration.

Abstract: ABSTRACT OF THE DISCLOSURE         A hydraulic safety valve manifold system for providing positive opening and closing of a surface-controlled, sub-surface safety valve in a subsea well, including a shut-off valve which prevents leakage of well fluids to the outside environment if a leak should occur in the safety valve or in hydraulic lines which are connect-ed to the hydraulic actuator of the safety valve.  A hydraulic control line is connected to the safety valve actuator through a normally closed shut-off valve, and this line is also connected to the actuator of the shut-off valve to hold both the shut-off valve and the safety valve open when the line is pressurized.  The hydraulic line is also connected to an actuator of a variable volume accumulator to empty the accumulator when the line is pres-surized.  When pressure in the hydraulic line is relieved the shut-off valve closes and the accumulator accepts fluid from the hydraulic actuator of the safety valve to insure that the safety valve closes.

Abstract: ABSTRACT    Dihydroxyaluminium sodium carbonate is prepared by reaction between an ionic aluminium salt and a stoichiometric excess of sodium carbonate in aqueous medium in the presence of sodium hydroxide at a pH in the range 7.2 to 10.5.  An amount of sodium carbonate at least ten times, and preferably fifteen times, by weight that of the aluminium salt is used and/or sodium salt by product,but not sodium carbonate, is precipitated from the aqueous medium.  Preferably, the sodium salt is precipitated by saturation of the aqueous medium with sodium carbonate and sodium salt by-product at a sodium carbonate concentration less than the invarient concentration for sodium carbonate and consequently at a sodium salt by product concentration greater than the invarient concentration for sodium salt by product.  The sodium carbonate-containing aqueous medium after separation of sodium salt by-product is reused as a source of sodium carbonate for subsequent reaction with additional aluminium salt.

Abstract: LIQUID LEVEL. RECORDER APPARATUS AND.METHOD   FOR STORING LEVEL DIFFERENCES IN MEMORY                     Abstract A shaft position recorder apparatus and method are described which can be used for recording changes in liquid levels.  The recorder employs an electronic memory for storing the changes in liquid levels which are entered into the memory at predetermined time intervals if they exceed a predetermined magnitude or "deadband".  The recorder appa-ratus employs a shaft position encoder as an input means for supplying a group of pulses for each measured change in shaft position or liquid level so that the sequence of the pulses indicates whether the change was an increase or decrease from the previous reading.  The preferred shaft encoder includes three reed switches which are operated by four permanent magnets mounted on a support disk which rotates in accordance with the position of the shaft, such shaft being coupled to a float pulley when used as a liquid level recorder.  The reed switches are closed in different sequences when the support disk is rotated in opposite directions to produce the groups of pulses on three parallel outputs connected to a computer for analysis to determine if levels change is up or down; and to produce a present level signal.  The recorder contains a temporary or scratch pad memory which stores a datum reference signal correspond-ing to the previously measured liquid level signal.  This datum reference signal is compared with the present level signal to produce a difference level signal corresponding to the differences in their amplitude which is then compared with a predetermined deadband limit signal to produce an output difference level signal when it exceeds such deadband.  The output difference level signal is period-ically gated every 15 minutes to a permanent memory to update the datum reference signal.  In addition, the recorder includes a maximum level memory and minimum level memory which continuously monitor the present level signal, temporarily store and transmit maximum and minimum level signals through gates to the permanent memory at the end of a predetermined time period such as every 24 hours.
